CONTROLLED WORK ZONE - CRITICAL PARTS

The last sign you’ll ever need.

Printed signs fade and fail—CNC-carved HDPE is permanent.

Precision CNC-carved from a .25” thick, sheet of solid Color Core HDPE, this is not a printed or laminated sign—it’s built to withstand indoor or outdoor industrial environments without peeling, fading, rusting, or rotting.

This CONTROLLED WORK ZONE – CRITICAL PARTS, ANSI-style Caution sign is designed to clearly identify restricted work areas where critical aerospace or defense components are handled, assembled, or inspected. It helps prevent unauthorized access and improper handling that could compromise product integrity, safety, or regulatory compliance.

This sign has a YELLOW background with BLACK inner core color, compliant with ANSI Z535 standards for the “CAUTION” category.
